Title: Ink injection printing head
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J2/04
Filed: 1988-12-20
Abstract: PURPOSE:To increase an ink pressing force and to reduce the propagation of vibration or deviation energy to the other by providing a driving electrode by electrostriction at a tuning fork type vibrator and a detecting electrode for detecting the vibrating deviation to form a self-excitation loop. CONSTITUTION:A tuning fork type vibrator 5 is formed of vibrator parts 5a, 5b and a coupling part 5c. If the vibrator 5 is contracted upward and elongated downward, the vibrator parts 5a, 5b are opened in a separating direction. In this vase, when the detecting voltages of detecting electrodes 6a, 8a are inverted to be amplified by an inverting amplifier 12, it is further energized. This is repeated to continue automatic vibration. When the automatic vibration loop is closed, the vibrator 5 is vibrated laterally, the ink 2 of the part P2 is affected by compression force and elongation force by the opening and closing of the vibrator parts 5a, 5b, and ink is extended as waves of perpendicular direction to the paper face. Part of the wave arrives at a nozzle 1a to generate an uneven wave at the boundary. When it is shifted from a crest to a trough, the ink is disconnected to fly in an ink particle 3. Since the uneven waves are generated plural times, a printing dot is formed by a plurality of ink particle 3.
